Another well-known form of Obsessive-Compulsive Disorder is Superstitious OCD. Often times, this form of OCD can be mistaken for someone that is superstitious about life. These individuals can believe in good or bad luck, good or bad numbers, or fear that if they don’t do something in a certain way or a certain number of times, something bad will happen. Common physical compulsions can include a certain ritual or routine to encourage compliance with the good luck practice to avoid bad luck. Mental compulsions can include the need to end counting on a certain number, type of number, etc. Other compulsions can also include the need to say things a certain way, do things a certain way, and wear a lucky shirt, hat, or some other article of clothing.
